Pabrik Nichrome Alloy Strip sakaNi80Cr20Ni70Cr30 Ni60Cr15 Ni35Cr20 Digunakake ing Perkakas Rumah Tangga
Ni70Cr30 minangka campuran nikel-kromium austenitik sing cocog kanggo aplikasi suhu nganti 1250 ° C. Isi kromium sing dhuwur (rata-rata 30%) nyedhiyakake wektu urip sing apik banget, utamane ing aplikasi tungku. Ni70Cr30 ditondoi dening resistivity dhuwur, resistance oksidasi apik, ductility apik sawise nggunakake lan weldability banget.
Ni70Cr30 digunakake kanggo unsur pemanas listrik ing tungku industri. Aplikasi khas yaiku: tungku listrik lan enamel, pemanas panyimpenan, tungku lan kiln kanthi atmosfer sing ganti.
Sifat Mekanik Khas (1.0mm)
- Elongation: 30%
- Kekuwatan Ngasilake: 420Mpa
- Kekuwatan Tarik: 810Mpa
